Energy storage in a fuel cell with bipolar membranes burning acid and hydroxide

Energy, 1983, vol. 8, issue 4, 277-282

Abstract: A battery is described, in which bipolar membranes are used to split water into acid and hydroxide. The liquids may be stored for an indefinite time, and energy may be recovered at room temperature. It is shown that the liquids are able to store about 400 kJ/litre, which roughly corresponds to pumping water up to an altitude of 40 km. Bipolar membranes of low area resistance have been made and tested. The area resistance appears to have been 2–3 Ω cm2. A battery containing 7 unit cells has been constructed and tested. The maximum output voltage has been 1.8 V. The cost for energy storage is estimated to range from $0.1 to 2.5 per kWh depending on the mode of operation.
